Find the area of shape 1 and shape 2

You can use Pick's theorem, where:

Area = Number of interior points (points inside the polygon) + · Number of boundary points (points on the polygon's perimeter) - 1

so:

1.Yellow:

Interior points = 3
Boundary points = 8



2. Red:

Interior points = 2
Boundary points = 10

Ihave, but this question is gonna probably get deleted.
